The recent deaths of two white dwarf stars are challenging our understanding of both novae and the powerful physics underlying star death. According to astronomer John Monnier, the initial analysis of these often dramatic novae offers an "extraordina...
Inside every human cell, an extraordinary feat of molecular organization takes place. Roughly six feet of DNA has to be packed into a nucleus that is only about one-tenth the width of a human hair, yet the DNA must remain accessible enough to carry o...
A study published in the scientific journal Communications Earth & Environment proposes that volcanic activity may have contributed to the rapid movement of the Black Death across medieval Europe. According to the researchers, cooling associated wi...
For more than a decade, cosmology has been stuck with a puzzling contradiction. Two of the most trusted ways of measuring the universe's expansion give two different answers. One set of measurements, based on nearby stars and exploding supernovas, ...
Ancient 'Dirty Dishes' May Have Led Archaeologists Astray for Decades Olive oil has been a kitchen staple for around 8,000 years, so archaeologists often report finding olive oil residue on excavated pottery. However, a new study published in the...
